sors.

The ECM (engine control module) is directly pow-
ered by the battery. It is responsible for the fol-
lowing engine management/electrical functions:
– analysis of information
– distribution of information
– start/stop function
– timer
– DESS (Digitally Encoded Security System)
– ignition timing control
– injection control
– proper mapping (injection and ignition) for opti-
mum engine operation in all conditions.
– engine RPM limiter
– etc.
The ECM features a permanent memory that will
keep the programmed tether cord cap (s) active,
fault codes and other engine information, even
when the battery is removed from the vehicle.

gagement speed only if a programmed tether cord
